UNSPSC 51283401: Penicillin o

This classification denotes a penicillin antibiotic with the molecular formula C13H18N2O4S2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 6246WH0S1O, chemically known as sodium (2s-(2alpha,5alpha,6beta))-6-((allylthio)acetamido)-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylate but generally known as almecillin, which bears US NIH Compound Identifier 23569. European Medicines Agency schedules Almecillin in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB05345MIG.

The term ALMECILLIN is an International Non-Proprietary Name or INN (see WHO INN reference publication, Volume 12 No. 2 1999, List 40). ALMECILLIN is scheduled in the U.S. International Trade Commission's Harmonized Tariff System (HTS) Pharmaceutical Appendix. SMILES: S1C2N(C(C1(C)C)C(=O)O)C(=O)C2NC(=O)CSCC=C.[NA].

UNSPSC 51283401 Penicillin O is a Commodity code for a specific antibiotic pharmaceutical product; however, recent state and local procurement activity tagged under this code does not reflect penicillin procurement. The two most recent opportunities in the dataset involve different pharmaceutical categories entirely — an Illinois Department of Public Health piggyback pharmaceutical warehouse contract for Doxycycline Hyclate and Ciprofloxacin Hydrochloride tablets, and a Seminole County, Florida IFB for Naloxone and Safe Drug Deactivation Systems. The mismatch between the code's nominal scope and actual recent solicitation content suggests either a cataloging error in the state and local procurement system or a tag applied in error. State and local issuing bodies using this code are primarily state-level health departments and county health authorities sourcing through cooperative purchasing vehicles and competitive invitation-for-bid processes.

Recent activity appears concentrated in the Southeast and Midwest. The Illinois Department of Public Health awarded a $2,999,999.11 three-year contract through the MMCAP Infuse consortium to Chartwell Rx LLC (Solicitation 26482DPHPREPDB53392, completed August 28, 2026) for bulk pharmaceutical supply on a piggyback basis, while Seminole County, Florida issued an IFB (IFB60459723LAS, due July 26, 2023) for 1,900 annual units of Naloxone and 800 Safe Drug Deactivation Systems with quarterly delivery to its Community Health Building. Given the divergence between the code definition and observed procurement activity, this code may not be a reliable signal for penicillin-specific opportunities in state and local procurement.
